Characterizing decoherence rates of a superconducting qubit by direct microwave scattering

npj Quantum Information, 2021
We experimentally investigate a superconducting qubit coupled to the end of an open transmission line, in a regime where the qubit decay rates to the transmission line and to its own environment are comparable.

Enhancement of the Λ decay rate [PDF]

Physics Letters B, 1996
The enhancement $ ( _b)$ of the $ _b$ decay rate due to four-fermion processes of weak scattering and Pauli interference is calculated within the quark model. An estimate of the relative $bu$ wave function at zero separation, $| (0)|^2_{bu}$, is obtained in terms of the $ _b^* - _b$ hyperfine splitting, the $B^* - B$ hyperfine splitting, and ...

Decay of a plasmon into neutral modes in a carbon nanotube

, 2010
We evaluate the rate of energy loss of a plasmon in a disorder-free carbon nanotube. The plasmon decays into neutral bosonic excitations of the electron liquid.

Fano-ADC(2,2) method for electronic decay rates

, 2020
Fano-ADC is a family of ab initio methods for prediction of electronic decay widths in excited, singly- and doubly-ionized systems. It has been particularly successful in elucidating the geometry dependence of the inter-atomic decay widths in clusters ...

Light-meson leptonic decay rates in lattice QCD+QED [PDF]

, 2019
The leading electromagnetic (e.m.) and strong isospin-breaking corrections to the $\pi^+ \to \mu^+ \nu[\gamma]$ and $K^+ \to \mu^+ \nu[\gamma]$ leptonic decay rates are evaluated for the first time on the lattice.

Stability on 3D Boussinesq system with mixed partial dissipation

Advances in Nonlinear Analysis
In the article, we are concerned with the three-dimensional anisotropic Boussinesq equations with the velocity dissipation in x2{x}_{2} and x3{x}_{3} directions and the thermal diffusion in only x3{x}_{3} direction.

Modelling memory decay after injuries using household survey data from Khartoum State, Sudan

BMC Medical Research Methodology, 2018
Background Injuries represent an important cause of morbidity and mortality worldwide. In retrospective epidemiological studies, estimated rates of reported injuries often decline considerably when information is included from periods more than a few ...

Inverse method for estimating respiration rates from decay time series [PDF]

Biogeosciences, 2012
Long-term organic matter decomposition experiments typically measure the mass lost from decaying organic matter as a function of time. These experiments can provide information about the dynamics of carbon dioxide input to the atmosphere and controls ...

Atom in a coherently controlled squeezed vacuum [PDF]

, 2006
A broadband squeezed vacuum photon field is characterized by a complex squeezing function. We show that by controlling the wavelength dependence of its phase it is possible to change the dynamics of the atomic polarization interacting with the squeezed ...
